Played a control deck in round 1.  It has a ton of tapping cards (Will of the Naga, etc), but I was able to bolster my team continuously and eventually push damage through.  Game 2 I played a UB deck that was extremely creature heavy, with mega morphs and fliers.  I was not able to out aggro or remove enough and ended up losing the round.  I played Nolan in round 3 and crushed his slower, more powerful deck in 2 games.
